WATCH-CASE PENDANT.

SPECIFICATION forming part of Letters Patent No. 482,971, dated September 20, 1892.

Application filed October 26, 1891. Serial No. 409,819. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES ARTHUR, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in VVatch-Case Pendants, of which the following is a specification.

My invention relates to an improvement in pendants for watch-eases, the object thereof being to so construct an article of this kind that the several parts may be secured together without the aid of the small pin or screw usually employed for this purpose, and which, passing through the crown, detracts from the I 5 appearance of the case.

With this and other ends in View my invention consists in certain novel features of construction and combinations of parts, as will be hereinafter described, and pointed out in :o the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of the pendant, the several parts being in position for winding the movement and opening the case. Fig.

2 is a similar view showing the parts in position for inserting the movement into the case. Figs. 3 and 4 show several views of detached parts of the device.

As will be hereinafter understood, one feature of my invention is the utilization of the standard sizes and shapes of crowns and pendants-that is, the use of a crown A, having a long core a, threaded to receive the end of a winding-arbor B, of the usual diameter,

3 5 throughout its length, in order that the extreme end of said winding-arbor which bears against the case-spring (not shown) will be sufficiently large to overcome all danger of its passing or forcing its way through the open- 0 ing in said spring; also, the utilization of a pendant C, having the restricted neck 0.

D represents a section of awatch-case center of the ordinary construction, having the pendant C soldered or otherwise secured thereto. The upper part of the pendant is chambered or hollowed out, as shown at f, and has tightly fitted therein a sleeve E, the outer extreme end of which has an inwardly-extend ing flange or shoulder e.

B represents the winding-arbor, threaded the greater part of its length and having its outer end screwed into the long core a of the crown, its inner end adapted to engage with the case-spring to open the lid and also to engage with the movement-winding mechanism. 5 5

F represents a sleeve, the lower portion of which is restricted in diameter to fit the restricted neck of the pendant, and has thus formed thereon a shoulder f which when the several parts are secured together fits against the end of the core a. This neck or restricted part f of the sleeve is threaded to fit the arbor B, the upper part being vertically slitted, as at f and slightly flared outwardly and having its extreme upper orouter end slightly rounded off, as shown in Fig. l of the drawings.

In the upper part of the sleeve is formed a groove or recess f, in which fits the flange 0, formed on the sleeve E, when the parts are in the adjustment as shown in Fig. 2.

Before securing the parts together the case maker by filing or cutting off that end of the winding-arbor which is threaded into the crown can properly fit the arbor to bear on the spring, thus allowing my improved device to be utilized with a case of any spread-a feature not found, so far as I am aware, in any other device of this character. To properly fit the winding-arbor to the case, it is simply 8o necessary to screw said winding-arbor into the crown, as shown in Fig. 3, and insert the same into the pendant after the latter has been affixed to the case, whereupon the proper length of winding-arbor can be determined. After the winding-arbor has been cut or filed down to its proper length it is then detached from the crown and the sleeve Fthen screwed thereon from the outer end, after which said outer end of the winding-arbor is screwed go home into the crown. The sleeve is then screwed outwardly toward the crown until the shoulder f thereon binds tightly against the end of the core a. It will thus be seen that the sleeve acts as a lock-nut to securely hold 5 the winding-arbor to the crown and overcome all danger of either the winding-arbor turn ing in the crown or the sleeve turning on the winding-arbor. The winding-arbor, having the crown and sleeve tightly secured thereon, is then inserted in the pendant and forced inwardly until the flange c jumps into the groove or recess f, as shown in Fig. 2. It will be understood that when the several parts are in this position the movement may be easily inserted in the case.

To adjust the parts to wind the movement, the crown is slightly pushed toward the case, whereupon the spring-ar1ns formed by slitting the sleeve F will be slightly compressed toward the core of the crown until the flange e jumps over the extreme end of said sleeve, when the arms will spring outwardly to their normal position. It will now be seen that my invention is exceedingly simple, can be manufactured at a small cost, and can be easily and readily adjusted to ditferentsized cases.

I do not broadly claim a sleeve threaded into the winding-arbor and slitted to form spring-arms, as I am aware that such construction is not new in the art.

I am also aware that it is not new to construct a pendant with a sleeve or spring-j aws held in position bybeing attached either to the winding-arbor or the pendant or by being bound between the arbor and the hub of the crown, such constructions being shown, for instance, in Patents Nos. 287,001 and 378,959. In these cases, however, the sleeve does notoperate as a lock-nut, nor does it allow of any adjustment of the parts, as in my device, wherein the sleeve, instead of being attached to the arbor, is threaded thereon and binds against the hub of the crown, thereby acting as a locknut to hold the arbor from turning in the crown and allowing of the end of said arbor to be out or filed off to adaptthe pendant to any spread of case.

What I claim as my invention is- 1. A watch-case pendant constructed with a winding-arbor threaded into the crown and a sleeve threaded onto said arborand against the hub of said crown, thereby acting as a locknut, said sleeve being slitted to form springarms, substantially as described.

2. A watch-case pendant constructed with a winding-arbor threaded into the hub of the crown and a sleeve having a restricted neck threaded onto the winding-arbor and against the said hub of the crown,thereby acting as a lock-nut, and being slitted to form springarms, substantially as described.

In a watch-case pendant, the combination, with the pendant fitted internally with a flanged sleeve, of a winding-arbor threaded the greater part of its length, a crown having an elongated core, into which latter said arbor is threaded, and the sleeve F, threaded onto said arbor and provided with the shoulder f to fit against said core, to operate in the manner and for the purpose substantially as described.

4:. In a watch-case pendant, the combina tion, with the pendant havinga flanged sleeve E fitted therein, of the arbor B, threaded the greater part of its length, a crown A, constructed with a long core a, into which said arbor is threaded, and a grooved and slitted sleeve F, having the restricted neck f, threaded onto said arbor and formed with the shoulder f adapted to bind against the end of said core, substantially as and for the purpose described.

Signed at New York, in the county of New York and State of New York, this 12th day of October, A. D. 1891.

CHARLES ARTHUR.
